    Saggital T1-weighted image Show a small mass,well circumbscribed, hypointense compared with brain, adjacent to nasal cartilage

     
    Area of Interest: unknown; Imaging Technique: MRI;

    Saggital T2-weighted image Show a discretly heterogenous hyperintense mass

     
    Area of Interest: unknown; Imaging Technique: MRI;

    Saggital gadolinium-enhanced image Show enhancement in the border of the well circumscribed mass

    dermoid cyst

    The incomplete regression of the embryonic nasofrontal diverticula with trapping of nonglial tissue result in nasal dermoid sinus and nasal dermoid/epidermoid cyst.
